This reverts commit e17af1c9d861dc177e5b56009bd4f71ace688d97.
Removing the delay of 100 units broke hot plug detection for USB-C displays on
qcom sc7180 lazor devices. Lazor uses mdss for hot plug detection and declares
dp_hot_plug_det in the dts. Other sc7180 based devices like aspire1 were not
affected by the regression, as they do not rely on mdss and dp_hot_plug_det for
hot plug detection.
